Finnish research helps ensure air quality
VTT Technical Research Centre of Finland has developed a device for the simultaneous measurement of several gases indoors.
The innovation can be used to measure ammonia and formaldehyde concentrations indoors together in real time. This distinguishes it from other meters currently in use.
“The device is capable of measuring the concentrations of several gases reliably and continuously with a sensitivity of less than 10 ppb, and it reports the results rapidly in just a couple of minutes or, if necessary, in seconds,” says senior scientist Timo Rajamäki from VTT. “The prototype can be flexibly modified for different purposes.”
Emissions from interior design and construction materials are a common cause of indoor air problems. The device is also suited to the measurement of emissions reducing outdoor air quality in city centres and traffic.
